Be it known that I, ANGELO Poomnsn, a subject of the King of Italy,residing at New York, in'the county of New Yorkand new and usefulImprovements in Nonskid Treads for Vehicle :VVheels, ofwhich thefollowing is a spec1ficat1on.-

This. invention relatesto certain new and useful improvements innon-skid treadfor.

vehicle wheels and more .particularly'to a tread adapted for mountingupon .a matic tire of an automobile wheel.

"The primary object oftheinvention is to 7 provide a non-skid tread forvehicle wheels:

wherein the tread is formedof resiliently 7 connected link sections orunits transversely curved coincident tozithe curvature of the treadportion of apneumatic tire with a connecting cable" for the unit atfeachside thereof for anchoringthe same upon a tire.

With the aboveandI otherobjects in view as the nature ofthe"invention-isbetter understood, the same consistsiof ithenovel; form,combination and arrangement of parts hereinafter more fully described,

accompanying drawing and present invention showing the resilientlyconnected tread sections, and the cable and clamp for anchoring the sameupon a wheel.

Figure 3 is an end elevational view of'another tread section,

Figure 4 is a fragmentary top plan view of one of the tread sectionsshowing the web connected anti-skid lugs or spurs,

Figure 5 is a detail sectional view taken on line V-V of Fig. 2 showingthe rubber bumper or block interposed between the anchoring clamp andwheel felly,

pneumatic tire and Referring more in 7. detail to. the acconi panyingdrawing, there is-illustrated av nonsigned for automobile wheelsequippedwith pneumatic .tlres, the noirslnd tread being formed ofpaplurality ofjsections 1 and a1 skidtread for vehicle Wheels, especiallydc single section 2, shown in detail'in Figures 2 and f 1 Each; of thetread sectio'ns includes 7 a' tread plate. 3, transversely curved coincii dent to the curvature ofthe tread portion pneu of the tire A andcarrying uponthe outer."

face thereof a plurality of. anti-skidstuds or spurs' of variouslengths,as shown in F igs- 2 and 3 topresent the outer terminal I andinalinement, certain ones of said spurs being connected by a web 5: as"shown in Fig. 4.

The opposite ends of the sections l at-each side thereof carry inwardlydirected -arms'6 provided with outwardly rected lugs? upon the terminalendslth'ere- The 1 outer faces of, the lugs beiugrapertured asat 8 asclearly shown in Fig. 3;

:of'the; arms 6 intermediate the ends there- I of, are provided withaperturedears 9, and

when the'sev'eral tread sections are mounted" upon the tire A, coilsprings'lO'connect the adjacent'apertured ears 9jat each side ofthetire. 1. f

'Inwardly directed arms 6 and 11 are carried by the opposite ends'ofeach side of the tread section 2; the arms G carry out wardly directed"apertured lugs 7 and apertured ears 9 for association with the ad jacentcoil spring 10. The arm-11 is provided with an aperturedear 9intermediate its end, asshown in Figs. 1" and 2, while a diagonal bracebar 12eXtends between the arm 11 and the tread plate 3 of the section 2.Thefree end of each arm 11 carriesan outwardly directed flange :13withfwhich i U-shaped shackleor clamp is associated, the clamp-embodyingan intermediate bariportion 14 inclosing the innerface of the felly B ofan automobile Wheel and carrying outwardly directed arms 15 providedwith screwstuds 16 upon the ends thereof that pass through openings inthe flanges 13 tobe retained therein by the clamping nuts 17, the freeend of each arm'l5 being provided with an outwardly directed aperturedlug 18. As shown in Figs. 2,5 and 6, an inverted U-shaped rubber bufferblock 19 i interposed between the wheelfelly B- and i the central barportion 14 of the shackle or clamp to prevent damage 'to the felly. Thetread-sections 1 and 2 are further anchored 21 carried by the diagonalbrace bar 12 shown in Fig. 1, the cable 20 passing through the aperturedlugs 7 and 7 and carrying at its opposite end a screw bolt 22 thatpassesthrough the'apertu'redlug'iTS of the clamp andanchoredtherein'byithe lock the free ends of the arms, cables extending "nut23.a

From theabove detailed description oit'the device, it is belieyed thatthe construction and operation'thereof will at once be -ap-' parent,ritbeing noted that the severaltread sections 1 and 2 are resilientlyconnectedby the. intermediately positioned coil springs 10 while theconnected tread sections areanchored onthe' tire and :felly by theshackle or clampand thecables 2-0. 1

, While there-is herein s'hown and described the preferred embodiment-ofthe presentinv rention, :it is nevertheless to be understood that minorchanges may :be made therein without departing from the spirit-and scopeof the invention as" claimed.

Whati sicl-a.irned as new is Y 1. In anon-skid tread for vehiclewhee-ls,

a plurality ofineta'llic tread sections having anti-skid tread faces,inwardly directed arms carried by each section, co l springsconnecting'the end arms o-fadj acent sections,

cables connecting theseveral sect-ions and a clamp tor anchoring thesections to a wheel telly.

ing anti-skid tread faces, resilient comree= tions between adjacentsections, a clamp attached. toenact the sections and :adapted tOIIl'Cl'OSG a wheel folly and-cables connecting the several sections andanchored to the clamp. v r 3. In a non-skid tread for vehicle Wheels,

directed arms at each side adjacent the ends. coil springs connectingt-he end arms of acen't'sectlons, 'a-pertured lugs carried by throughtheiapertured lugs withone of their ends anchored to a tread section,and a clamp lnclosnug a Wheel telly and secured ends of the cablesanchored thereto. a

4. Inia non-skidtread for vehicle wheels, a plurality of metallic.treadsections having a; plurality of :metal-lic tread sections hay-'ing anti-skid tread faces, each section being transversely curved andhaving inwardly ltocne ofthe tread sections 'withlthe other anti-skidtread ntaces, each section being 7' transversely curved and havinginwardly directed armsIat eachside adjacent the ends,

coil springs connecting-the endflarms of adqace'nt sections, aperturedlugs'carried by the free ends'of the arms, cables extending through the:apertured lugs with one of their ends anchored toa itread section, a

I U-shaped-clamp having the intermediate portion inclosing a wheelfelly, a cushion butter interposed between -the clamp. and telly,outwardly directed -flanges 1 carried by the arms of-one ofthetreadsectio-ns, scren-' bolt connections between the clamp arms and flangesand; apertured lugs carried by the clamp arms to which the other endsoiithe cables are'attached. v. i a

In testimony whereof I atfix ny signature.
